This invention appertains to new and useful improvements in the generalart of illumination and more particularly to a light especially adaptedfor sick room use.

The principal object of the present invention is to provide inconjunction with the usual standard room lighting fixture a dim andshaded light which would not only light up the switch, but would alsoafiord a dim light for the room.

During the course of the following specification other important objectsand advantages of the invention will become apparent to the reader.

In the drawings:

Figure 1 represents a front elevational view of the switch plate andswitch with the auxiliary light mount.

Figure 2 represents a vertical sectional view taken substantially online 22 of Figure 1.

Figure 3 represents a diagrammatic view disclosing the electricalcircuit when the auxiliary light is of low voltage and suitable candlepower.

Figure 4 represents a diagrammatic view showing the circuit employedwhen the auxiliary light is of substantially the same voltage as thehouse light but small wattage.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Figure 2 that numeral 5 represents the wall of a sickroom and numeral 5 represents the switch boxlike plate which is providedwith a slot 7 in its front through which the snap button 8 projects. Atthe top of this switch box-like plate 6 a hood 9 is provided and thishood has an inclined wall MB for supporting the lamp socket H whichreceives a small bulb 92. In the upper portion of the switch box likepiate 6 a shelf 53 is provided to support the small snap switch M forthe bulb E2, the switch i l and lamp l2 being connected by wires 55 inseries with the step down transformer It, the opposite sides l'ii3 ofits input being connected into the light switch circuit l9 branched fromone of the main wires A, which circuit l9 and I90, contains the usualbright room light bulb 25]. Obviously, the lights l2-2il areindependently controllable through the switches M-8, it being apparentthat the bulb I2 can be energized by closing the switch M withoutaffecting the lamp 20.

Figure 4 represents the bulb H as Hot and has a bulb of substantiallythe same voltage power but small wattage as the standard room light 20.Aside from being of the same wattage, the transformer I6 is eliminatedand the wires I5 are mere- 5 1y connected into one of the circuit wiresof the lamp 20.

It can be seen that a fire alarm is included in the system and isclearly shown in the diagrammatic views of Figures 3 and 4. This alarmcon- 10 sists of the connection 2i across the secondary of the step downtransformer, and in this connection! are the electrodes 22 whichprotrude into the goose-neck portion 23 at the upper end of thethermometer 2G, and also in this connection 2| is the buzzer 25. Thethermometer 24 has the mercury bulb 26 at its lower end and this isfinally seated in the depression 27 of the front wall of the plate 6,while the upper goose-neck portion 23 eX- tends through an opening 28 inthe upper portion of the plate 6.

In the event a stepdown transformer it is not employed as hereinbeforementioned, the connection 2i is made in the manner shown in Figure 4.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit orscope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed is:

An illuminated switch for a room lighting circuit comprising anelongated supporting panel, a switch for the room lighting circuitbehind said panel with an operating lever exposed through said panel, adepending hood secured to the upper portion of said panel, a socketsecured beneath said hood in a position to illuminate said lever, anelectric light bulb in said socket, a switch receiving compartment insaid hood, a switch in said compartment for controlling the energizationof said bulb and a transformer receiving compartment in the lowerportion of said panel for reducing the line voltage for the bulbcircuit.
